How a flat roof survey works in Long Marston
If the house you are buying has a flat roof on an extension, dormer or garage, it is worth knowing its condition before exchange. Many felt roofs need renewing after around 15 to 20 years, and EPDM and GRP frequently go on for longer. Our report records the covering, how it is holding up and any defects we can see, with photos of each. You then have something specific to put to the seller or agent. If you’ve noticed upstands pulling away from walls and a sagging deck under the covering, we can find out what’s behind it.
Some older homes in villages like Long Marston are listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. If you’re planning work, check with the council first. Knowing the roof’s condition is the starting point. Listed building consent is needed for changes that affect a listed building’s special interest.
If any part of the flat roof couldn’t be seen safely, we say so in the report. That way, it is clear what was covered and what wasn’t.

DIY checks: what’s safe
After strong wind, take a look from the pavement or garden: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Don’t go up yourself.
What you can’t do safely is get up close. Roofs are fragile and slippery, and a fall can be serious. That part is for a survey, using safe viewpoints and a drone where it applies.

What we can’t see
Without opening up the roof, some things stay hidden, so a survey has limits:
- An exact number of years the roof has left
- The condition of the deck or insulation hidden under the covering
- Asbestos testing, which needs a specialist asbestos surveyor

What a flat roof survey looks like in Long Marston
About 4.3 miles north lies Ascott House, a reminder of how long the area around Long Marston has been built on. If you own one of the older houses, expect a mix of original materials and later repairs on the roof, and any change of roofing material on a listed home needs checking with the council first. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates, with flat-roofed extensions, dormers and garages common everywhere. Next to the main roofs there is typically a flat roof somewhere, whether on an extension, a garage or a commercial unit.
Landlords with a home close to Cheddington station may find that flat roofs over rear additions and dormers in rented property are worth checking between tenancies. If you look after a building like Long Marston VA Church of England Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

Your questions about flat roof surveys in Long Marston
Does a conservation area affect roof work in Long Marston?
We cannot confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case.
Do you cover smaller places like Long Marston?
Yes, Long Marston is covered. We cover the whole of London and South East England, and smaller places are part of that. Longer journeys are simply planned ahead of time.
What’s in the report?
Written findings with photos, covering the condition of the flat roof, the defects we found and what we recommend, by urgency where it matters. Standard adds moisture detection and a structural check; Premium adds thermal imaging, drone inspection where it applies and structural analysis.
Are you structural engineers?
No. Our survey is not a structural engineer’s report, and it doesn’t include calculations. We’ll recommend an engineer if we see signs that call for one.
Can you survey a shared roof?
Yes, once access has been agreed. The roof of a block or converted house is often shared, so whoever owns or manages the building needs to agree access. We can only inspect what we are given access to.
How long have you been surveying roofs?
We have more than 20 years’ experience and have carried out more than 5,000 surveys across London and the South East.
How long is the visit?
Most surveys take about 1–2 hours on an ordinary house, rising to roughly 3–4 hours on a commercial building. We’ll confirm the timing as you book.
Landlords, agents and block managers in Long Marston
We also survey roofs for businesses and commercial landlords, including offices, shops and units. Bigger roofs take more time.
If the property is let, the agent or a tenant can let us in. We survey on any day of the week, which helps when tenants work during the week.
Why get it checked now?
Caught early, a split or open seam in a flat roof is often a small repair. Left alone, water can soak the insulation and the deck, and the job grows. A survey now shows which you’re dealing with. Older and listed buildings around Long Marston may need consent and matching materials for repairs, so a defect found early gives time to plan the work properly.

How it works
We look at the roof from outside and, where it is relevant and there’s safe access, from inside the roof space too. In the loft, the signs we look for are staining, damp, daylight and sagging. All in, the survey normally takes about one to two hours at a typical home, and more on a big or complicated roof. For a village or hamlet like Long Marston, the journey is planned ahead of time: let us know about narrow lanes, gates, long drives and where we can park. The roof is looked at from ground level, from windows, from the loft where there is safe access and from the roof where it is safe.
- We start with the details: the address, the roof’s use and any leaks or stains.
- We check the roof from wherever it can be seen safely.
- Every part of the roof we can see is looked at: covering, falls, upstands, outlets, trims and rooflights.
- Where there’s safe access, we look at the ceilings and spaces below for signs of water.
- We send a written report with photos, the defects we found and what we recommend.
Before we arrive
- If it isn’t your property yet, arrange access through the agent
- If the roof is shared, arrange access with whoever manages the building
- Point out any leaks or damp patches
Getting a price

Advice
Do you need a flat roof survey in Long Marston?
Flat roofs frequently get walked on for other jobs: to clean windows, fit aerials or air conditioning units, or reach a gutter. Each visit can damage a covering not made for regular foot traffic. Fixings added through the covering often start leaks too.
Most people get in touch when they’ve noticed something like this:
- Ponding water that doesn’t drain away
- Blistering in felt or asphalt
- Blocked or damaged outlets
- Signs of deflection in the roof deck
If you live in an older home near Church of All Saints (Church of England), the flat roofs on later extensions tend to wear out long before the main roof.
What to check before booking
- How they’ll see the roof: from the ground, the loft, the roof or by drone
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- What’s outside the scope of the survey
- Is there a chance to talk the report through?
